A method for monitoring the amount of moisture sprayed on a moving material web or a roller across their width, with the width being divided into individual measurement areas includes a measuring step, a storing step and further measuring steps. The measurement is made of local droplet flow of the sprayed liquid in the individual measurement areas, storing the measured values as set values, and again measuring the local droplet flow and comprising it to the set values. The device used includes a counting device and an evaluation unit. The counting device registers droplets of the liquid sprayed on the moving material web in a respective one of the individual measurement areas, and generates a signal per registered droplet which is supplied to the evaluation unit.
